Banjo Bolt Fittings

The banjo bolt fitting has a hollow bolt that is installed through a round hollowed out chamber with a hose fitting incorporated onto the chamber. The hollowed out chamber and hose fitting resemble the shape of a banjo, hence the name banjo bolt. The banjo bolt uses a sealing washer on each side of the hollowed chamber that should be replaced during reassembly.

Banjo bolt fittings are used where the fluid in the fluid lines is under pressure.

To remove a banjo bolt type of fitting:

Secure the component the banjo bolt is threaded into and loosen the banjo bolt using a boxed end wrench if room permits.
